John Samuel Raven (1829-1877) was an English landscape painter.
Raven was born in Suffolk in 21 Aug. 1829. He was the son of the Rev. Thomas Raven, a clergyman of the Church of England, who had considerable talent as an amateur artist, as may be seen from six water-colour drawings by him in the South Kensington Museum.
John Raven was, however, almost entirely self-taught, initially by studying the works of John Crome and John Constable. He exhibited at the Academy as early as 1845, and his works also appeared at the British Institution. This part of his career was focused on views of the area where he lived, near St. Leonards[disambiguation needed]. He at first fell under the influence of the Norwich school, but his maturer works, which show much poetic feeling, bear traces of pre-Raphaelitism. It was his custom to prepare elaborate cartoons for his pictures. He was drowned while bathing at Harlech in 13 June 1877.
He married Margaret Sinclair Dunbar in 1869.
